Atomic force microscopy is a novel method for imaging and characterization in biomedicine. However, high-resolution imaging of living samples from cells to tissues still remains a challenge. In this paper, two types of AFM working mode (contact mode and tapping mode) which are utilized for the imaging of living cells and tissues are discussed. A new magnetic tapping mode (MAC mode), which is more suitable for living samples, and a novel data collecting system named TREC, are also introduced.
Activating Blood Circulation to Remove Blood Stasis(ABCRBS) has long been the most fundamental therapeutic principle since the age of Yellow Emperor(circa 2600 BC) in Chinese medicine.Based on bio-responses of blood shear stress,which was not considered in Chinese medicine,we have initiated the merging of biomechanics with pharmacology and Chinese medicine,establishing the new discipline-biomechanopharmacology.Practice of exercise is a simple and self-regulatory way to promote shear stress in the circulation.Interestingly,acupuncture and massage are also linked with shear stress regulation.These procedures are expected to maintain normal functions of endothelial cells(ECs) by regulating shear stress levels of flowing blood.The statement of "Diseases are prevented as blood flow is promoted" by the renowned ancient physician Huatuo,who presented the wise foresight of the efficacy of shear stress,would likely begin a new chapter in preventive pharmacology and medicine in the years to come.
